Indoor Air Quality Monitor Buying Guide

Now that you’ve finished reading our air quality monitor reviews, you may want to learn more about these devices.

Below is a helpful guide that covers every aspect of indoor air quality monitors.

You can use this information to gain additional knowledge on how these units work and the types of pollutants air quality monitors can detect in your home.

What is an Air Quality Monitor?

Best air quality monitor

An air quality monitor is a device that measures the level of air pollutants. Air quality monitors are available for both indoor and outdoor settings and can detect PM2.5, PM10, carbon dioxide, formaldehyde, nitrogen dioxide, VOCs, temperature, humidity, and air pressure.

An air quality monitor collects data on pollutants to show you what needs to be improved in an indoor or outdoor setting. The more in-depth your air quality monitor is, the easier it will be to determine what issues in the air require improvement.

Many people use home air quality monitors for different purposes, including to support their research studies, inform the general public about pollution levels, to measure indoor air quality at home, and to show a business whether they’re producing too much pollution or not.

How Does an Air Quality Monitor Work?

Air quality monitors work with lasers and sensors to detect pollutants in the air, such as particulate matter (PM2.5), VOCs, carbon monoxide, radon, etc. An air quality monitor can also work to measure the temperature, humidity, and air pressure.

Some air quality monitors offer the readings instantly while others can be programmed to record measurements in intervals.

And every air quality monitor works differently in the sense of the types of pollutants it can detect and how it can be used (via Wi-Fi or as a standalone visual unit).

Types of Home Air Quality Monitors

Portable Air Quality Monitors

Portable air quality monitors offer the most convenience for the user.

These units can be taken anywhere that you want to assess the air quality as no wires are tying you down.

Most portable air quality monitors display the readings on the device, giving you a simple way of reading the data it’s collected in a visual form.

Wi-Fi Smart Air Quality Monitors

Wi-Fi smart air quality monitors are connected to and controlled by your smartphone through an app.

Inside the app, you can read the data for every pollutant that’s detected. You can also check this data from anywhere because you don’t have to be physically near the monitor to see what’s going on.

Wi-Fi smart air quality monitors provide the most in-depth analysis in regards to pollution measurements and allow you to customize the data in various ways. That’s what makes this type the best home air quality monitor for many people’s needs.

Keep in mind that some Wi-Fi smart air quality monitors are not portable; they must be plugged in at all times in order to work. Many of these devices are designed to stay put in one location without being moved around the home.

Handheld Air Quality Monitors

Handheld air quality monitors are the last type of unit on the market. And they’re some of the most basic monitoring systems available.

As the name suggests, you hold these monitors in your hand to get a reading. They are very portable and do not require wires to plug in for power.

Professional air quality specialists prefer this type of air quality monitor because they can walk around and measure the pollution levels wherever they go. These devices also tend to have simplistic controls and deliver basic readings and analysis for common pollutants.

Features to Look for in a Home Indoor Air Quality Monitor

Best indoor air quality monitor

Precision

Unfortunately, not all consumer air quality monitors are as designed with the same technologies and do not give you the same level of precision of pollutant detection.

The air quality monitor you choose needs to give accurate readings for the contaminants and air quality issues you deem to be most important.

For example, one air quality monitor may detect VOCs, CO2, and HCHO, but not PM2.5 which is fine particulate matter that can get into the deep recesses of the lungs.

Alternatively, another air quality monitor may be able to measure PM2.5 but not the level of VOCs (volatile organic compounds) in the air which are toxic chemicals.

Most air quality monitor brands tend to focus on a small set of pollutants to measure rather than all of them. This is because the more the unit can detect, the more technology has to go into it, and therefore the price increases.

To avoid spending too much on your air quality monitor, you should determine which pollutants are most important for you to detect and choose a monitor that can sense them accurately.

Response Time

The higher the quality of the monitor you choose, the faster response time you expect from the readings. This is because the sensors tend to be more accurate with higher quality air quality monitors so they can gather important information at a much faster rate.

Another factor that might affect the response time of your air quality monitor are the pollutants you’re monitoring. If the pollutant is particularly dangerous to your health, the response time might be considerably less because the device needs to measure it with the most accuracy.

An example of this is when you’re monitoring carbon monoxide (CO) levels. If the air quality monitor detects a small amount of the gas in the air, then it might inform you after a couple of hours.

However, if there are dangerously high levels of carbon monoxide in the air, then  it will notify you within minutes so you can leave the area. 

Ease of Use

Depending on your prior experience with air quality monitors, you should find a model that you can use with ease. Some units are best for beginners while others have lots of high-tech features that are better suited for advanced users.

Single or dual-pollutant detectors are some of the easiest monitors to use as they don’t require much effort on your part. You can literally set them up and then quickly read the measurements on the device without any hassles.

Advanced air quality monitors that detect numerous pollutants and give you the option to display the data in numerical or graph form can be overwhelming for some users. However, some people enjoy this added level of granular data when monitoring their home air quality.

Remember that there’s no shame in getting the simple model; it will save you hours of researching how to use all of the complex features that you may not even use.

Size

Although air quality monitors are relatively small in size, they do come in various heights and widths.

When shopping for a good unit, you may want to consider the size and placement of the device. 

For example, if you need a portable air quality monitor that can be easily taken from your home to the office, then you’ll want a unit that can fit in your pocket.

On the other hand, if you’re going to place the air quality monitor inside your home to measure the pollutants in your living room, then the size may not even matter to you. So choose the size accordingly.

Portability

Expanding on from the previous feature, some people like to use their air quality monitors on job sites or in multiple different locations. If you want to carry your monitor around with you, then you should focus on the size, weight, and shape of the model.

Strangely shaped air quality monitors might be a little difficult to move around as opposed to the rectangular or handheld design you’ll find on the majority of models on the market.

Wi-Fi Smart Control

Wi-Fi smart control air quality monitors are easy to use for beginners and allow you to track the data from your smartphone or tablet. 

You don’t necessarily need a monitor that boasts this feature, but the majority of new models do give you this level of control.

To use a Wi-Fi smart air quality monitor, all you need to do is connect the unit to your home’s Internet router so that you can get the data onto your phone. Then inside the proprietary app, you can get insight into the information you’re looking for.

The app will show you the recorded pollution data as it’s recorded over time. Some brands even allow you to set up push notifications to alert you when particular air pollutant levels get too high so that you can make an action plan to remedy it.

Power Supply

Air quality monitors are either battery operated, powered by USB, or get its power from an electrical outlet.

If you wanted a portable monitor to take around with you to different locations, then you should look for a battery-powered air quality monitor or one that recharges through USB.

On the other hand, if the monitor is going to be left in one spot in the house, then you can choose a corded alternative.

Pollutants That an Air Quality Monitor Can Detect

Depending on the type of air quality monitor you buy, it can detect one or more of these various types of pollutants.

Allergens

Allergens often enter the home from outside, where there are many more pollutants. Pollen, dust, emissions, and smoke are just some of the allergens that can reduce the quality of your air. 

Allergens can be bad for your health when breathed in, particularly in large quantities. And an air quality monitor can help you uncover invisible allergens that may be affecting your well-being.

Bacteria and Viruses

Bacteria and viruses can enter your home in several different ways, and when breathed in can make you ill. These pollutants are not always harmful to humans, but it’s better to know whether they’re inside your home or not. 

Air quality monitors can be vital in preventing you from getting sick from viruses or bacteria in the air. While some are more difficult to detect than others, you can still be better prepared once knowing the quality of your air. 

In rooms with high humidity levels, bacteria and viruses thrive. So if you’re aware of the relative humidity inside your home, then you can look for ways to lower it in order to kill off these microorganisms and pathogens.

Carbon Monoxide (CO)

Carbon monoxide (CO) is a dangerous gas. It is lethal, yet you cannot taste, smell, or see it. For this reason, it’s important to monitor CO levels if your house includes a fire burning appliance. 

According to the Consumer Product Safety Commission (CPSC), “CO levels increase and remain above 70 ppm, symptoms become more noticeable and can include headache, fatigue and nausea. At sustained CO concentrations above 150 to 200 ppm, disorientation, unconsciousness, and death are possible.”

Carbon Dioxide (CO2)

An increased amount of carbon dioxide (CO2) in the air will prevent there from being enough oxygen. This can cause breathing problems and difficulties. 

Kane International reports that concentrations of CO2 below 1,000 ppm indicated good air exchange is occurring indoors.

Formaldehyde (HCHO)

Formaldehyde (HCO) is rather common and yet not widely known about. It is a chemical that can be released from daily household supplies and building materials. 

Having HCHO in the air can result in several health issues, but only in high concentrations. It’s normally present at low levels (less than 0.03 parts per million) in both indoor and outdoor air. 

The Occupational Safety and Health Administration states, “the permissible exposure limit (PEL) for formaldehyde in the workplace is 0.75 parts formaldehyde per million parts of air (0.75 ppm) measured as an 8-hour time-weighted average (TWA).”

Mold Spores

Mold spores are an irritating allergen that can affect your health, potentially causing an allergic reaction in some people. Red eyes, rashes, sneezing, and a running nose are common symptoms of inhaling mold spores. 

If you or someone in your family has asthma or allergies, an air quality monitor that detects mold spores can be extremely helpful. 

Mold spores can promote asthma attacks and uncontrollable allergy symptoms, so keeping your air clear of them can prevent these. 

Ozone (O3)

Ground-level ozone (O3), when breathed in, can irritate your lungs and pose a threat to your health. 

According to this research, “O3 in residential buildings mainly comes from two sources: outdoor atmosphere and indoor ozone produced by electrical devices.”

So knowing the level of O3 in your home can be important for health and safety.

In this report by the Environmental Protection Agency (EPA), “The Food and Drug Administration (FDA) requires ozone output of indoor medical devices to be no more than 0.05 ppm. The Occupational Safety and Health Administration (OSHA) requires that workers not be exposed to an average concentration of more than 0.10 ppm.”

PM2.5

PM2.5 stands for particle matter that is smaller than 2.5 microns in diameter, which are the most dangerous to your health. 

As you can imagine, these pollutants are very small and cannot be seen by the naked eye. Examples of PM2.5 are combustion particles, metals, and organic compounds.  

Measuring PM2.5 can be crucial when determining air quality as an increase in exposure can lead to a number of serious health issues: lung damage, cancer, brain disease, heart attack, central nervous system damage, etc.

The Environmental Protection Agency (EPA) indicates that anything above 35.5µg/m3 in a 24-hour period is considered too high a level of PM2.5.

Radon

Radon is the second leading cause of lung cancer in the United States after smoking. 

Radon comes from naturally radioactive elements, such as uranium when it breaks down over time. Underground heating and ventilation can speed up this process and allow the gas to get in through the flooring.

Detecting indoor radon and mitigating it is important and a home air quality monitor can help with that.

Volatile Organic Compounds (VOCs)

Volatile organic compounds (VOCs) are very common when it comes to indoor pollution as they are released from the use of many indoor supplies, such as cleaning products and aerosol spray. However, VOCs are also found in paints, sprays, adhesives, building materials, furniture, and other common household items that you may not suspect.

VOCs can be harmful to your health when exposed for short and long periods of time. So it’s good to know the level of VOCs in your home in order to make an action plan to remedy it.

Fortunately, most of the best indoor air quality monitors can detect VOCs

Temperature

Indoor temperature is always important to know. And an air quality monitor can report this measurement for you.

Humidity

The correct humidity level is important when it comes to preventing pollutants from taking over your house. 

Keeping a relative humidity of 30 to 50% is recommended to prevent mold growth and dust mites from accumulating. Low humidity can also deter bacteria and viruses from surviving inside the home.
